General description

LY-294,002 hydrochloride is a derivative of the flavonoid, quercetin and elicits higher inhibition on the enzyme phosphoinositide 3-kinase (PI3K). LY-294,002 inhibits nuclear factor kappa B signaling in macrophages. It elevates expression of autophagosomal protein LC3 and promotes apoptosis in gastric and nasopharyngeal cancer cells. LY-294,002 modulates action potential repolarization and improves myocyte contractility.


LY-294,002 hydrochloride has been used in the inhibition of:
  • phosphoinositide 3-kinase (PI3K) in human lung cancer cell line
  • autophagy in mesenchymal stem cells (MSCs).
  • serine/threonine-specific protein kinase (AKT) signaling in fibroblasts and cardiac cells.

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.
